The assembly date and VIN on the trans will be on the flat pad (towards the tailhousing) across from the drain plug and where it says U.S. Patent. It is the flat pad where the mid-bearing plate is bolted up against.

Spray some carb or brake clean on it and the numbers should appear.

That's a casting number. The numbers you are looking for are on the axle tube, between the center carrier and the backing plate. They are usually on the side facing forward, but can be almost anywhere on that tube. They will be recessed from a hand held stamp, not raised as part of the casting.


Here's a pic of the assembly code you are looking for.

Just because you can turn one axle and the other one doesn't turn doesn't mean it's not positive traction. I've been telling people for more than 30 years that this is a completely unreliable way of testing a rear end. You will have to remove the cover to see what is in it. Look for a code stamped into the front of the right axle tube. The casting number that you posted is a common casting used for all Camaro and Nova 12 bolt rear ends that year. The stamped code will tell you what it is.

Yeah, Here is an example pic. I had the wrong side.

Hope you are having some luck getting codes off the rear and bell housing.
